Nuclear fusion may be closer than you think too. We've been developing better and better superconductors that could yield more compact and more powerful electromagnets, which is a major bottleneck to making it practical. ITER is huge and fabulously expensive, but it's intended to be more of an experiment/testbed that happens to maybe generate some power. It's not intended to be a practical reactor.
